I felt that the plastic part seemed to end soon but it was surprisingly firmly tightened After that it is an aged deterioration Even though it is a knob that is familiar to the hand and easy to turn I think that it is good

To firmly tighten the GOLF club during grip exchange. There are synthetic rubber and natural rubber for grips, and it takes time to attach synthetic rubber firmly. Using a hose band is better than natural drying.

I used a small pump to pump water from the canal near the home garden, but the loose insertion of the hose was loose and I was in trouble often. There is no problem at all after fixing with this hose band.

Usability of resin knob is very good.
It can easily be fixed securely.
We recommend choosing the maximum diameter of the hose to be used + the size of α.
(Choosing a size that is too large will make your ease of use worse.)
